after reviewing this forum. it seems as if infiniti g35 have a big issue with the programming of the remote. or fob.i cant get both remotes to work 1 is brand new was working fine an the other came with the car was working fine...both batterys died so i replaced them NOW nothing cant get them to activate the car... i took to get them tested the remote pass the function test. something deffinitly wrong with infiniti . and i believe the should recall this problem. since everyone is having the same issue.
